ChemViz3D

What ChemViz3D is

ChemViz3D is a free web tool for teaching chemistry with interactive 3D molecular scenes and reaction animations. Students can rotate, pause, and zoom in on atoms and bonds, while a keyframe editor lets learners and educators build custom reaction sequences. Animations can be shared by link and opened in a browser without installing software. Its molecule toolkit supports structure analysis and visualization, with SVG or MOL downloads. An image-to-SMILES workflow accepts uploaded files, pasted screenshots, or image URLs, and supports .smi and .mol exports. ChemViz3D can also turn .chemx or .json animation files into Python scripts for Blender. The product describes using PubChem PUG-REST and NCI/CADD services for molecular data and structure resolution. It says it is used in UTS chemistry courses and was developed with guidance from two UTS professors. The individual learning and teaching plan is free, with no sign-up required. The full interactive reaction player requires WebGL, and a modern desktop browser is recommended.

Who it suits

ChemViz3D suits chemistry learners and educators who want to explore molecular scenes or create and share reaction animations in a browser. Individual use is free, but institutional, LMS, enterprise, redistribution, and product integration use requires permission or a separate licence.

Getting started

1. Open https://www.chemviz3d.com/ in a web browser
2. Start with the free Individual learning and teaching plan; no sign-up is required
3. Use the molecule toolkit to analyze or visualize a structure, or open a reaction scene
4. Use the keyframe editor to create a custom reaction animation
5. Share an animation by link or export supported files

Verdict

ChemViz3D combines interactive molecular scenes with tools for making, sharing, and exporting reaction animations. Its full player depends on WebGL, and broader institutional use requires permission or a separate licence.
